Quizplus · Accepted Answer

The dopamine system, which is involved in reward and motivation, and the insula, which is involved in processing emotions and bodily sensations, have both been shown to play critical roles in the development of addiction. In particular, the release of dopamine in response to drug use can create an intense feeling of pleasure that reinforces drug-seeking behavior, while the insula may be involved in the negative emotions and physical sensations that drive individuals to continue using drugs despite negative consequences.
